Mount Lindesay Arterial Road (Beaudesert Road) and Illaweena Street, upgrade intersection (known as the Beaudesert Road and Illaweena Street intersection upgrade)

A detailed design is being developed for the Beaudesert Road and Illaweena Street intersection upgrade project, Calamvale/Parkinson.

This intersection regularly experiences high traffic volumes, with around 35,000 vehicles travelling on Beaudesert Road per day and around 10,000 vehicles travelling on Illaweena Street and Algester Road daily in 2020.

Upgrading this intersection will help to manage congestion along Beaudesert Road and improve safety for all road users.


  • Reduces travel time
  • Improves network efficiency
  • Improves safety
  • Reduces peak hour congestion
  • Contributes to economy
  • Increases capacity
  • Increases traffic flow
  • Better active transport


The Queensland Government has committed $30 million for this project as part of the Queensland Economic Recovery Strategy: Unite and Recover for Queensland Jobs. Investment ID 1190346

Concept design

We have developed a concept design for the Beaudesert Road and Illaweena Street intersection upgrade. The proposed concept design includes:

  • widening Beaudesert Road to 6 through lanes (3 in each direction)
    • tying into the existing 4 lane road north of the intersection
    • tying into the existing 6 lane road south of the intersection
  • extending the right-turn lanes into Algester Road and Illaweena Street
  • replacing the left-turn slip lanes into Algester Road and Illaweena Street with signalised left-turn lanes
  • bus stop improvements:
    • a new bus stop on Illaweena Street
    • an upgraded bus stop on Beaudesert Road to improve customer access.
  • constructing a shared pedestrian and bike riding path adjacent to the Beaudesert Road northbound lanes by using the existing service road 
  • constructing a protected intersection with separated bike riding lanes and other safety features to protect cyclists.

Protected intersection

A highlight of the design is a fully protected intersection, which includes innovative design features to separate bike riders from general traffic and pedestrians so all roads users can safely share the intersection. 

While there are other intersections in Brisbane that have protective features for bike riders, this upgrade will deliver a fully protected intersection, providing a safer and more predictable environment for all road users and encouraging more people to get on a bike and keep active.

An example of a fully protected intersection was recently completed at Albert and Lansdowne streets in Melbourne—watch a video about this intersection.
